I am a university student who has been doing research and development on a Hybrid Rocket system based on ABS/Paraffin fuel. We have been doing static fire tests on the research side, but what exactly are the legalities of taking a hybrid motor platform that I created and flying it in a home built rocket? Outside of the academic environment, I would love to personally integrate our rocket motor into a rocket and fly it (This is assuming that I "own" the rocket motor design and that it is not a matter of academic propery). I understand there are issues in making solid fuels that are Inherently explosive, but what about Hybrids where the fuel is Inert and the oxydizers are available and not illegal?
